Golly. I don't even know why I bother when other people can make things like this (kidding... sort of).
This does not feel like a jam game at all; it looks amazing, it feels great, and there appears to be a good amount of content. The central mechanic is unique and fun and difficult and weird and fun. You've somehow made it the perfect balance of unwieldy to control, but controllable enough that I don't get frustrated and quit. It just feels so fun to bounce around.
I love the goofy story and character designs too. Everything stylistically works together and it only enhances the good goofiness of the gameplay.
Overall, amazing work.
